Ship an AI App People Can Actually Trust
Maps to: AI Application Builder · Software Engineer · Product Manager · AI Engineer · Founder
You're going to build an AI app that does a real job for a real person. Then you're going to make it good enough that they can actually depend on it. The skill is finding where it gets things wrong, deciding how right is right enough for your person, and fixing the mistakes that matter most. This is what the people who build AI for a living spend most of their time doing, and it's turning into a real career. By the end, you'll have an app someone can actually depend on.
You're done when: An AI app, online, doing a real job for a real person, a list of test questions covering the normal, the weird and the sneaky, a written line on how right is right enough, the worst breaks fixed, and a short honest note about where it still fails. Getting it right every time is the work: not 'it works when I show it off,' but 'I can show exactly where it breaks and what I did about it.'
How this shows up on a resume or college app
I built an AI app for a real user and made it dependable: I wrote a list of normal and deliberately sneaky test questions, found where the AI failed, decided how right it had to be, and fixed the worst breaks. I learned that connecting an AI into a product is the easy part, and that making something unpredictable trustworthy enough for a real person to rely on is the actual work.

The plan
- 1
Step 1
Get a first answer, then define 'good'
Open a chat with Claude or ChatGPT and get it doing the real job right now, for a real person. It'll get some answers right and some wrong, and the wrong ones are the whole point: write down the 5 examples your app absolutely has to get right. These become your test questions later.

Step 2-3
Build the first working version
Now build it. Put an AI to work inside a simple app, or set up a chain of steps (pieces connected together that run one after another by themselves, so you don't have to do each one by hand), so it does the job on your 5 examples. Don't make it perfect yet. You want something that mostly works, so next you can test it until it breaks.

Step 3-4
Try to break it: write hard questions and run them
Here's the part that makes this a real AI app and not a party trick, something that looks cool once but doesn't actually work when it matters. Grow your 5 examples into 10 to 15 test questions, the examples you keep testing the app against, and make the new ones HARD: odd wording, missing information, things people might try to trick the app into doing that it shouldn't, weird one-off situations nobody expects. Try all of them on the app and write down, for each one, whether it got it right or wrong. You'll watch it get some wrong in ways that surprise you. That's the job, not something wrong with you.

Step 4-5
Decide how right is right enough, then fix the worst
Now you decide. Look at what went wrong and decide: for YOUR person, how right does the app have to be? What should it simply refuse to do, no matter what's asked? Which mistakes MUST you fix, and which can you live with? There's no right answer here: an app a friend messes around with and an app somebody actually relies on need different levels of care. Make the call, then fix the worst mistakes: better instructions, firm rules or a flat refusal (telling the app exactly what it must never do, no matter what), or a way for it to say 'I'm not sure'.

Step 5-6
Give it to a real person, and write what you learned
Give it to one real person and watch them use it. They'll trip it up in a way your list never imagined, and that gap between your test questions and real life is the most useful thing you'll learn on this whole project. Then put the app online: instead of it only running on your own computer, like a file only you can open, you publish it so it lives on the internet at a link, the same way a website does, and anyone can open that link and use it. Add a short honest note about where it still gets things wrong.
